What is a wave?

When most people hear the word

“wave” they immediately think of

waves in the ocean…

So lets begin learning about waves by

observing this type of wave in action.

What is a Wave?

Scientists define a wave as….

A repeating disturbance (vibration) that moves through a

medium carrying energy from one location to another.

Medium: a substance or material that carries the wave.

A Wave Transports Energy and Not Matter

Journal Entry: Is “The Wave”

really a wave? Explain.

Waves: Day 3

Warm Up

Stand up paddle boards

(SUP’s) were first used

by pacific islanders to

travel between nearby

islands. Why bother with

paddling? Why not just

surf waves the whole

way across like a rad

surfer dude?

Defining Waves

Wave: A repeating

disturbance (vibration) that

moves through a medium

carrying energy from one

location to another.

Medium: a substance or

material that carries the

wave.

A Wave Transports Energy

and Not Matter

Quick Quiz: Would this be a

wave?

Is there an initial

disturbance, or energy

input?

Is energy transported from

one point to another?

Is there a transport

medium?

Is the energy transported

through the medium, with

the medium itself returning

to it’s original position? NOT A WAVE

The Great DebateIsaac Newton: Light energy is

carried as a packet of energy.Christiaan Huygens: Light

energy is carried as a wave.

Then along came Thomas Young

“Young’s Double Slit Experiment”

Technically your both right…

So what is the medium for light?
